Intel 520 240GB SSD RAID 0 Performance Review

Read Bandwidth

For this benchmark, HDTach was used. It shows the potential read speed which you are likely to experience with these hard drives. The long test was run to give a slightly more accurate picture. We donít put much stock in Burst speed readings and thus we no longer included it. The most important number is the Average Speed number. This number will tell you what to expect from a given drive in normal, day to day operations. The higher the average the faster your entire system will seem.

As with any RAID configuration, sequential speed is basically double that of a single drive.

Write Performance

For this benchmark HD Tune Pro was used. To run the write benchmark on a drive, you must first remove all partitions from that drive and then and only then will it allow you to run this test. Unlike some other benchmarking utilities the HD Tune Pro writes across the full area of the drive, thus it easily shows any weakness a drive may have.

Once again, the speeds of the RAID array are basically double that of a single 520 240GB drive. Actually it is slightly higher than twice but this minor variance is well within tolerances.

Inexpensive, good performance and an awesome warranty; OCZ's Trion series seems to have everything we could want in a value-oriented SSD. But with the Crucial BX100 and MX200 out there, how well does...
